A drive-by-wire automobile steering system comprises a mechanical electric steering device composed of two driving motors and a set of mechanical steering mechanism, and the two driving motors can simultaneously or independently provide operation power for the mechanical steering mechanism under the control of a main controller in the drive-by-wire automobile steering system. The mechanical steering mechanism receives operation power provided by at least one driving motor to complete operation actions, and therefore steering of the automatic driving automobile is achieved. According to the mechanical electric steering device with the dual-driving motor redundancy design, the drive-by-wire automobile steering system which can ensure that steering can be controlled as required even if one driving motor breaks down and the driving safety of the self-driving automobile is ensured is provided for the self-driving automobile, and the self-driving steering requirement of the self-driving automobile is met; and a mechanical steering mechanism in the mechanical electric steering device can have various forms, and is simple in structure, reliable in work, convenient to maintain and high in reliability and applicability.

    一种线控汽车转向系统,包括了两台驱动电机和一套机械转向机构所组成的机械式电动转向装置,且两台驱动电机可分别在线控汽车转向系统中的主控制器的控制下同时或单独为机械转向机构提供作业动力,机械转向机构接受至少一台驱动电机提供的作业动力即可完成作业动作,从而实现自动驾驶汽车的转向。本发明通过双驱动电机冗余设计的机械式电动转向装置,为自动驾驶汽车提供了一种即使一个驱动电机出现故障也能保证能够受控按需转向、确保自动驾驶汽车行驶安全的线控汽车转向系统,满足了自动驾驶汽车的自动驾驶转向需要;且其机械式电动转向装置中的机械转向机构可以有多种形式,结构简单、工作可靠、维修保养方便、可靠性和适用性强。
